Professional C# 2005 prepares you to software in C#, and it offers the mandatory history info on how the .NET structure works. It presents examples of purposes that use numerous similar applied sciences, together with database entry, dynamic websites, complicated portraits, and listing entry. the single requirement is that you're accustomed to no less than another high-level language used on Windows—either C++, VB, or J++.

It starts off with an academic on C# and the .NET framework. This advent assumes no earlier wisdom of .NET, however it does stream swiftly, at the assumption that the reader is an skilled programmer. as soon as this history wisdom is proven, the publication starts off to comb in the course of the substantial .NET type library, displaying how one can use C# to unravel quite a few tasks. This entire assurance is among the key promoting issues of earlier models of the publication, and is maintained and superior with this new version by way of including new chapters on Generics, ObjectSpaces, Yukon, and Indigo. a few reference fabric is incorporated both as appendices or is obtainable to obtain from the Wrox website.

After the creation and preliminary bankruptcy, the booklet is split right into a variety of sections that conceal either the C# language and its software in various parts. assurance includes:

This ebook provides the C# language in a uniquely succinct and visible layout. frequently in programming books, the knowledge may be hidden in an enormous sea of phrases. As a programmer who has through the years used a dozen programming languages, the writer is aware it can sometimes be difficult to slog via one other 1,000-page publication of dense textual content to profit a brand new language.

A Programmer's consultant to ADO. internet in C# starts by means of taking readers via a fast paced evaluate of C# after which delves into ADO. web. Why should still C# programmers use it rather than the present applied sciences? What new performance does it supply? The chapters that keep on with plow through the main points on all the significant facts services of the .

If you are a . internet developer, you will use C# even if you are development a sophisticated company program or simply slamming out a short app. In C# five you are able to do impressive issues with generics, lambda expressions, dynamic typing, LINQ, iterator blocks, and different gains. yet first you need to research it intensive.

Written with very transparent walkthroughs and step by step directions, this e-book includes many instances that essentially help you write higher code, refactor it and quick locate difficulties on your code. This ebook explains tips to begin utilizing ReSharper and the way you could configure it to fit your wishes. first and foremost it makes a speciality of introducing the main usual positive aspects that assist you in writing code and locate issues in smarter, swifter methods.

Full details are in the MSDN documentation. Arrays We won’t say too much about arrays in this chapter, because we cover arrays and collections in detail in Chapter 9. However we’ll give you just enough syntax here that you can code 1-dimensional arrays. Arrays in C# are declared by fixing a set of square brackets to the end of the variable type of the individual elements (note that all the elements in an array must be of the same data type). A note to Visual Basic users: arrays in C# use square brackets, not parentheses.

Specifically, it prohibits fall-through conditions in almost all cases. This means that if a case clause is fired early on in the block, later clauses cannot be fired unless you use a goto statement to mark that you want them fired too. The compiler enforces this restriction by flagging every case clause that is not equipped with a break statement as an error similar to this: Control cannot fall through from one case label (‘case 2:’) to another 49 Chapter 2 While it is true that fall-through behavior is desirable in a limited number of situations, in the vast majority of cases it is unintended and results in a logical error that’s hard to spot.

46 C# Basics Flow Control In this section, we will look at the real nuts and bolts of the language: the statements that allow us to control the flow of our program rather than executing every line of code in the order it appears in the program. Conditional Statements Conditional statements allow us to branch our code depending on whether certain conditions are met or on the value of an expression. C# has two constructs for branching code—the if statement, which allows us to test whether a specific condition is met, and the switch statement, which allows us to compare an expression with a number of different values.
